WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 498,905, dated June 6,1893. Application filed October 23, 1891. Serial No.409,597 (No model.)

T0 @ZZ whom t-ma/y concern:

Be it known that I, RICHARD M. SHAFFER, a citizen of the United States,residing at Baltimore,in the State of Maryland, have invented certainnew and useful Improvements in Water-Motors, of which the following is aspecification.

The object of my invention is to produce a jet motor capable of` beingoperated with a minimum amount of water without waste and that can beconstructed at aless cost than those made in the usual manner and tothis end I construct the same as fully set forth hereinafter and asillustrated lin the accompanying drawings, in which- Figure 1 is asectional elevation of a jet water motor embodying my invention. Fig. 2is a transverse sectional elevatlon. Flg. 3

is a view illustrating a modification.

The casing A of the motor may consist of two side disks 1, 1, and anintervening rim 2, as shown in Figs. l and 2, or it may consist of twopieces stamped up to form two sections 3, 3, connected together edge toedge as shown in Fig. 3. In either case there is a shallow box or casingpreferably round and transversely through this casing passes a shaft 4,which carries the wheel B, and is externally, provided with a pulley 5,for the reception of the band or cord.

The wheel B,is provided with blades which are made integral with thewheel and formed by radially slitting a disk 6, of thin metal for anydesired distance from the edge and then twisting each section betweentwo radial slits to bring it upon a plane at right angles to the diskand bending the alternate sections to the left and right so as to formtwo series of blades 8, 9, upon opposite sides of the plane of the diskand each substantially at right angles to said plane. By this means Iprovide awheel in which the body and the buckets are integral with eachother so that the buckets cannot become detached by imperfectconnections and I avoid the expense incident to making the buckets ofseparate pieces and securing them to the body. I further secure alighter structure than'would be possible if the blades were made inseparate parts and secured to the body byseparate fastenings. While thewheel may be made by slitting a disk by means of hand tools and bendingthe sections with pinchers a great reduction in cost may be secured bythe use of suitable stamps and dies that cut or slit and bend the partsat a single blow.

Instead of acting upon both series of blades with asingle broad streamall parts of which cannot act effectively I divide the stream intoseparate small jets one for each series of blades and project the sametangentially but at about right angles to the faces of the bladeswhereby each blade in succession receives the full force of the streamthat acts upon it and as the blades of the two series are arrangedalternately one stream is always acting with full force so that there iscomparatively little loss of eective action by the transfer of a streamfrom one blade to the next following while as the water is divided intosmall streams the full force of every particle of each stream is securedand there is no waste.

If desired the sections between the slits of the disk may be so bent asto form three series of alternating blades two 8and 9, being bent toopposite sides while the intermediate se-V ries occupy a radial positionon the blade between the other two forming a third series of vblades l0,as shown in Fig. 3. In such case the incoming water is divided intothree jets one in each series of blades.

While the streams may be conducted into the interior of the casing andformed by the use of any suitable nozzles I prefer in consequence of theeconomy of manufacture to make use of a block of metal or other suitablematerial C, bored at an angle to form channels 12, corresponding to thenumber of jets requiredall of said channels communicating with a recess13, threaded to receive a threaded nipple 14 upon the casing of a cockD, that connects with the inlet pipe A16.

The block C is placed beneath the recess in the peripheral part of thecasing, and thenipple 13 is passed through said recess into the threadedopening in the block, when the casing of the cock is turned until theperiphery of the casing A, is tightly clamped between the casing of thecock and the block C, and the latter is drawn tight and close. By thismeans the block and the cock are secured in position and a tight jointis formed which if desired may be luted or packed. At any suitable pointin the periphery of the casing is an opening az, for the escape of theluid after it has acted upon the blades. V

Without limiting myself to the precise construction andarrangement ofparts shown and described, I claim- The combination of the casing, thewheel having two or more series of blades, the channel block C having anozzle for each series of blades, and a cock D, having a nippleextending through the side of the casing and into said block,substantially as set forth.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing Witnesses.

RICHARD M. SHAFFER.
